That's one of the reasons. The other is that it provides snowball advantages dependent on how ahead you are. Crit, sheen procs, attack speed, and move speed are all much better stats when you're higher level than the enemy than when you're lower level. Triforce damage seems huge when ahead, and worthless when behind. You sacrifice survivability for the damage and utility it brings. Which, again, is fine you're ahead, but bad if you're behind

Gives you great midgame skirmishing, but Wukong is primarily a teamfight-oriented champion so building for mid-late can often be better.

At 20 mins Triforce is amazing, but at 30 minutes Cleaver+Mallet might be a lot better. Press TAB, look who is strong and who isn't and try to keep this in mind when shopping.

Same is true of a lot of Triforce users, Irelia for example great with his item, but Zephyr+Mallet scales better as it gives her more desirable stats as well as more utility.

One thing worth noting about Triforce is that it's damage does fall off lategame if you don't build Armor Pen, that said it is extremely slot efficient so its often worth keeping in a six-item build especially since the movespeed is fantastic all game long.

Wukong is a really weak lane matchup against the overwhelming majority of popular tops. He has an amazing transition into teamfights if you can hold your own through lane phase, but make no mistake, it's an uphill battle to get there. His ult is hands-down the best scaling ult in the game, so every bit of AD and ArPen goes a long way. Triforce does not have great synergy with his ult, only his dive combo, which makes it an incredibly single target-focused item on a multi-target champion.

How do you feel about wu in mid lane? I have tried it before a long time ago to some success. Might try it out some tonight. I feel like wu built as a assasin type character in the mid lane could be great

not so good imo, he cant really activate the sheen proc that often, and he's more of a sustained fighter rather than burst. then again ive never built it on him, so i take my advice with a grain of salt

oh he uses the ark speed and crit late game, you can usually get 1 more attack off before your 40%cdr q comes back by lvl15 and it stays til 18, not only doing more damage, but procing your passive lifesteal. it also let's him finish towers sooner

My friend often plays Trundle jungle. As he calls it, "the Trungle" and he has found that getting Triforce as an early item and then picking up Frozen mallet later makes Trundle impossible to escape. I would say that any champion that can make use of MOST of the stats and has an ability that can affect the next attack (Wukong's Q, Trundle's Q, Nasus's Q) will benefit greatly from having a Triforce.

His AD ratios are among the best in the game, and his base damage is paltry, up until level 11. He has an escape and a gapcloser. Bruisers are known for CC (of which Wu only has one) and sustained fighting, Wu's burst is over in 6 seconds max, and he has ridiculous burst. His only bruisery steroid is an attack speed roid that people use to finish off squishy targets, not engage the front line.

His kit is not designed for him to be a tanky DPS. You can build him like a bruiser to take advantage of his E steroid, but that's like building him AP to take advantage of his W (granted his W has shitty AP scaling and is incredibly difficult to land). He is very clearly designed to get in, Q-E-R, then use his escape to prevent being focus fired. Building him bruiser is just like building pantheon bruiser. Sure it works, but it's not optimal.

Wu mid devastates, placing him against squishy targets he can chunk really easily. His Q is low cost, low cd and the range is underestimated, it's easy to harass with. It shreds what little armor they have for potential follow up with your E, autos, and ult. His W can bodyblock many skillshots. Plus you hit level 11 first, and his level 11 is just too good to restrict to the island that is top lane.
